Late braking technique used by expert motorcycle roadracers in which the brakes continue to be applied beyond the point at which the motorcycle has been leaned over and has entered the corner.

The technique requires a great deal of finesse and skill in order to avoid the loss of front wheel traction, which usually results in a low side crash.
Any attempt at trail braking by a novice rider, although usually unintentional, almost invariably results in a low side crash.
